By default, the scope view (a.k.a. the aim down sight) has a fixed sensitivity that is unaffected by the in-game sensitivity setting. This means that if your in-game sensitivity is set very low, for example due to a high DPI mouse, the scope view will be too sensitive.

To fix this, we will need to adjust the internal Unreal engine mouse calibration.

In StormInput.ini, find the line MouseSensitivity and change it to a lower value, like this: (Default is 60)

MouseSensitivity=10

This setting affects both the scope view and the regular sensitivity, so you will also have to increase the sensitivity in-game after this tweak.

Here are the settings I run in-game. Of course, the graphical settings are subject to your card.
